I am having difficulty choosing a shower head and hand shower for our master shower. We currently have an older Grohe hand shower mounted on the shower arm and only use one setting for actual showering. Prices for showerheads seems to vary widely even in the same line; Ferguson quoted the following just for Grohe heads. When I asked about the price, they told me it was design elements only. Axor Citterio 3-jet 2.0GPM $474.16 4-function 2.0GPM $59.66 Movari 2.5GPM 5-function $175.60 Raindance S $374.34 Randance E $447.01 The best thing I could find was on the Rohl website, a video that actually showed each of their shower heads in operation. Ferguson quoted $175.30 for the Rohl Ocean4 showerhead. Do I just choose a basic rainshower for the main showerhead, and the multi-function for the hand shower? What is the correct placement of the hand shower in relation to the main shower head? (I've seen some where the hand shower bar is mounted so that the top position of the hand shower is parallel horizontally to the main shower, some so that the hand shower is down and over a foot.) Thank you in advance!

Brizo (Delta) has an articulating shower arm https://www.google.com/url?sa=i&source=images&cd=&ved=2ahUKEwjRlrKqlvviAhXnhOAKHaE4CVAQjRx6BAgBEAU&url=https%3A%2F%2Fwww.brizo.com%2Fbath%2Fproduct%2FRP81434PC&psig=AOvVaw2m6uruuH1tnPx6W5tGczv1&ust=1561227105736845

Did you want them to operate at the same time? I am in California so it is not permitted to use more than one water fixture at the same time. However I have two hand held shower heads and one fixed shower head and they are all controlled by my three way diverter. I have a thermostatic valve which controls the temperature - the diverter turns the fixtures on/off and selects the specific shower head. I would recommend a thermostatic control valve versus a pressure balance. It's slightly more expensive but much better. In my experience every decent plumbing line makes a three way diverter - pick the style of your fixtures and then have your GC and plumber order everything (rough and trim) so that he/she takes full responsibility for it being correct and available when needed.

Re: "whereas the Delta is an extension to a shower arm." - Purchase a chrome-plated 1/2" pipe nipple for the Delta and now the Delta can be an adjustable shower arm with extension as well. https://www.supplyhouse.com/Bluefin-CRN050-300-1-2-x-3-Chrome-Brass-Nipple-Lead-Free Re: "the [Litze] double joint may provide more flexibility for sitting closer to the wall." - Looking at my own Kohler 5" dia. shower head, it all depends whether with the Litze or Delta setup the open bell of the shower head would contact the piping or reside below it. If the bell contacts the piping, at most you're talking about a roughly 2" difference in closeness to the wall. I don't think that's enough to be concerned with. Re: "Th Delta ..... would need to be adjusted to a 90 degree angle to minimize the extension from the wall - this might be too tall." - When can a shower head be too tall? People nowadays pay good money to upgrade to a rainshower head. I'm not being facetious here, I honestly wonder. Re: Are "the joint[s] on the Litze and Delta ... fully adjustable?" - They most certainly should be. How can I say that? Well, from a manufacturing perspective it is a lot easier (and that means cheaper) to machine a circular recess for the seal at the arm joints than it would be to manufacture a step in the seal face in order to restrict the movement, and in industry today everything is about lowering the cost to manufacture a product. The Delta arm also looks to be over $100 less to purchase as well.
